Hi
This is patch for shared snapshots to be included in the next merge
window. The patch only adds new modules dm_multisnapshot and
dm_store_mikulas, it doesn't modify any existing code.
It already works with userspace code.
The disk format is supposed to be stable, there would be hopefully no more
changes to it.
The patch can be downloaded at
